zsh in GNU Screen--Login Shell?

zsh in GNU Screen--Login Shell?

[Aaron Davies]

Does anyone have any experience running zsh inside GNU Screen? On all 
the boxes I've used them on until now, zsh always started inside screen 
as a non-login shell--i.e., zshrc was executed, but not zprofile. 
However, just today I set up my usual environment on a box running 
GenToo linux, GNU Screen 4.00.01, and zsh 4.2.0, and it appears to have 
changed--zprofile seems to be executing too. This poses something of a 
problem, as my means of executing screen is through zprofile, so if 
when screen creates a new window, zsh calls zprofile again, I end up 
with nested screens, and a possible infinite recursion problem. Does 
anyone know why this is happening (or what I can do to prevent it)?

BTW, one example of a box that gives the correct behavior is Mac OS X 
10.3.4, zsh 4.1.1, screen 3.09.15.

Sure, I've used that combination for many, many years now (I think I was
using zsh back when I was maintaining screen, oh so many years ago).

I'm using debian with screen 4.00.02 and zsh 4.2.0 without this problem,
so it's probably something that has been customized by the gentoo folks.
It might be something as simple as them setting the shell to a value
that begins with a '-' in the /etc/screenrc file (or wherever it is on
gentoo these days).  Look for a line like this:

shell -$SHELL

In fact, I decided to rsync the app-misc/screen dir from portage (I used
to use gentoo a while back), and they have that exact line in their
screenrc file.  Just comment it out and you should be fine.

Thx much. It's actually not my box, so I don't have root. I assume an 
equivalent solution would be to add "shell $SHELL" to ~/.screenrc, thus 
overriding the global?

Yup, that's certainly the best way to solve it without root access.

Random aside:  doesn't this spell Aarom Davies? (with an 'm')?

Yes, it does, at least if you're seeing it in a fixed-width font, which 
I presume you are, since you're using Mutt. The thing on the end of the 
first name is supposed to be a cursive 'n', with some sort of trailing 
stroke after it. I've fiddled around with a it once or twice to try to 
get it to look more like an 'n', but never found anything I really 
liked. It was made by a friend of mine on his DOS box using an old prog 
called CURSIVE.EXE; I've tried to find a comparable font in FIGlet, but 
to no avail.

The source to cursive is at ftp://puck.nether.net/pub/janc/ if you want
to build it on Unix (there are also FreeBSD and Darwin ports in their
respective port trees).

Otherwise, "figlet -f cursive Aaron Davies" is very close.

I've had the following in my .screenrc for years:

# Use a login shell to make ssh-agent work
shell -zsh

Not any problem with it.
